And now, the precious parents are FINALLY sharing a sweet snap of Maddox Laurel Boss with the world! The Dancing with the Stars pro took to Instagram on Tuesday to show off her first child with her hunky husband, and it is just TOO cute!

Well there might only be one thing cuter than the adorable image itself, and that would be the glowing momma's caption! The So You Think You Can Dance alum's wife was full of fond memories of the day she first met Maddox, writing:

"On Easter Sunday I gave birth to our Son MADDOX LAUREL BOSS he was 8 lbs 15 oz and full of joy. He has already stolen my heart with is big bright eyes, stunning radiant smile and the way he snuggles perfectly into my arms, he is perfect in every way! He is and will always be my precious boy. And I feel so blessed to be his mother."

UGH! Our hearts are just melting! But wait, it only gets better!

The gorgeous gal also penned a little letter to the tiny tot, saying:

"To Maddox: I promise to love you forever, i will lead, I will teach, i will be strong, I will listen, I will be an example. I will be a shoulder to cry on when u need it, I will have a bandaid ready for when u fall, i will walk you into your first day of school and help u study for ur first test , I won't help teach u to drive ( leave that to dad, the one that is a good driver) but I will help u pin on ur first prom boutonnière. I will be there for it all and you every step of the way . I AM your mother and that is unconditional and everlasting!
I LOVE YOU MADDOX and welcome to our family."

This famous family is just PERFECT! We can't wait to watch Maddox grow up before our very eyes!

Zayn previewed the duet by posting a black and white pic of himself with Swifty on his Instagram -- but hey, she is bestiez with his girlfriend Gigi Hadid, so it wouldn't be unusual that they hang out... But collab?!
